Replying to I just witnessed the most disgusting thing in my entire life

well, the phone just rang and my parents are out in the hot tub right..., so i go bring the phone out to them and i stop dead in my tracks, this is painful for me to type, i saw my own mother naked in the hot tub next to my naked father, i even knocked before i went out.  Yes i understand that they are allowed to have sex but i really wish that they would do it in the privacy of their bedroom, or at least bring a phone out with them.  I'm going to go throw up now.
